I want to show you that Deep Convolutional Neural Nets are not nearly as intimidating as they sound. And I’ll prove it by showing you an implementation of one that I made in Google Sheets.

I'm sure you've read a dozen deep learning explainers, but actually demonstrating the concepts in a spreadsheet is so much more instructive than writing english sentences. Spend a few minutes with this even if you've used CNNs before—the spreadsheet is wonderful at building intuitions.
